ABSTRACT
The emergence of anatomically modern Homo sapiens in South Asia is hotly debated due to a great
gap in fossil record. A solitary partial cranium from Hathnora dated around 250 Kya is debated and
conveniently interpreted as “evolved” Homo erectus or “archaic” Homo sapiens or Homo
heidelbergensis or even Homo indet. Cranial fossils of Pre-Toba or post- Toba anatomically modern
Homo sapiens are unknown barring the very late 30 Kya modern human remains from Sri Lanka. The
present paper reviews the scenario of human evolution in South Asia with special reference to the
cranial and recent postcranial fossil findings by the author in association with the archaeological
evidences from Central Narmada valley. It is concluded that the Narmada fossils and archaeological
findings support the presence of three hominins- two ‘archaic’ and one ‘early modern’. The Mode 2
Acheulian hominin represented by the calvarium and the femur was a ‘large-bodied’ species akin to
Homo heidelbergensis. It appeared first in the Central Narmada valley and was followed by a ‘small-
bodied’ Mode 3 archaic type represented by two clavicles and the 9th rib, provisionally named here as
Homo narmadensis. It likely continued and attained anatomical and behavioural modernity in South
Asia as attested by the humerus and bone artifacts, and diversified to various short-bodied indigenous
populations of South Asia supported by the genomic evidences.

INTRODUCTION
Three pivotal issues confront palaeoanthropologists worldwide: (1) The Last Common
Ancestor of the Chimpanzee-Hominids, (2) the Homo erectus-Homo sapiens Interface, and
(3) the emergence of modern Homo sapiens. Indian palaeoanthropology can contribute
potentially for the understanding of these issues if Indian evidences are interpreted on their
own merits without preconceived views. Though there are a number of notable archaeologists
and mammalian palaeontologists in India, but she lacks practicing palaeoanthropologists to
defend and place Indian hominoid and hominid evidence on their merit.
Here, I shall focus on the second and the third aspects, and only touch upon the first
dealt with in greater detail in various publications (Sankhyan, 1988, 1990, 2007). The hunt
for the purported ‘chimpanzee-human’ last common ancestor (LCA) in African fossil records
has so far proved futile. Numerous fossils collected from all over the Old World reveal a
peculiar distribution pattern of the Late Miocene hominoids and Plio-Pleistocene hominids.

While African continent is rich or the only source of Early Miocene fossil apes between 14 to
20 Million years ago (Mya), it has demonstrated meager or fragmentary evidences of the
Middle to late Miocene hominoids between 13 to 7 Mya, a period crucial for the
differentiation of the ‘LCA’. This period both in Asia and Eurasia has demonstrated rich
occurrences and diversity of the hominoids, who essentially exhibit a more morphological
affinity between the Southeast Orangutan and the Plio-Pleistocene African hominids
(Schwartz, 1987; Grehan & Schwartz, 2009; Sankhyan, 1988, 2007); the focus has shifted to
Asia (Dennell and Roebroeks, 2005).
The Homo erectus- Homo sapiens Transition or H. heidelbergensis: When and Where?
Archaic hominin morphology fairly goes in line with Palaeolithic technological development
in the Old World. Large Flake Acheulian handaxe-cleaver technology of Homo erectus was a
great advance over the crude Olduwan choppers of Homo habilis. This made Homo erectus a
versatile hunter and a global trotter successfully adaptive to new environmental opportunities
expanding and populated tropical and subtropical zones as far as the South East Asia. This
migration could have not been possible without acquiring greater intelligence and better
hunting skills and use of fire. This territorial expansion most likely began around 1.8-1.7
million years ago and coincides with progressively cooling climate of Europe and Asia. By
half a million years ago, some Homo erectus populations were able to move into the
seasonally cold temperate zones of Asia and Europe. Surprisingly, however, Homo erectus
remained little changed anatomically until about 800 Kya, thereafter his brain expanded and
approached modern humans. The robust features like the sagittal ridge and torus angularis in
Homo erectus likely became vestigial pleisiomorphies simply retained in some later hominins
but vanished in other during evolution to Homo sapiens.
The transition from Homo erectus to Homo sapiens probably started as early as 400
Kya and 250 Kya. This was the later Middle Pleistocene in which we see a trend in brain
expansion and refinement in stone tool technologies. There are many morphologically
intermediate specimens discovered all over the Old World, which indicate continuity between
late Homo erectus and early Homo sapiens. Such intermediates are called “archaic” Homo
sapiens or also known by a new species, Homo heidelbergensis (Rightmire, 1998).
The type specimen of Homo heidelbergensis is Mauer 1, discovered in 1907 in the
Mauer sand pits near Heidelberg, Germany and most likely dates back to 500 Kya. Another is

600 Kya Bodo cranium with 1100cc brain volume which was discovered in 1976 at Bodo in
the Middle Awash Valley of Ethiopia. The Arago cave cranium (Tautavel) in the eastern
Pyrenees Mountains, France, has 1166cc brain volume and also appears to be Homo
heidelbergensis. The Petralona 1 cranium discovered in 1960 in Greece, dated to be around
400-300 Kya, originally attributed to Homo neanderthalensis, and later classified as Homo
erectus, is now attributed to Homo heidelbergensis specimens. It has a large double-arched
brow ridge, massive face and 1220 cc brain volume. There are other important specimens
like, Kabwe, Steinheim and Atapuerca, including the Dali cranium of China, all attributed to
Homo heidelbergensis. The Kabwe Man from Broken Hill in Zambia discovered in 1921 and
dated to 200-125 Kya is often cited as the example of typical Homo heidelbergensis in Asia.
It is a very heavy-boned complete cranium with large brow ridges and a receding forehead;
the brain size equals to that of modern humans.
The type specimen Mauer 1 shows a host of both primitive and derived features that
have been accepted as proof of ancestry to the Neanderthal line. In general, Homo
heidelbergensis specimens show a continuation of evolutionary trends that occurred in the
Lower Pleistocene into the Middle Pleistocene. Along with changes in robusticity of cranial
and dental features, there is a marked increase in brain size from Homo erectus to Homo
heidelbergensis. The striking morphological features of these are enlarged brain, divided or
curved brow ridges unlike a continuous rim of the Homo erectus of China and Java. It also
lacks the sagittal midline thickening of the braincase, occipital torus and thickened ear region
and mandibles of Homo erectus. Its skull shows moderate development with receding
foreheads lacking in Java Homo erectus compared to the Peking man. The difference is also
visible in the relatively larger brain volume; Homo erectus has 800-1000cc whereas Homo
heidelbergensis had 1200cc. The skull is conspicuously larger; it is longer and low-shaped
with relatively rounded braincase; the brow ridge was large but discontinuous, flatter face
without chin; its skeleton and teeth are usually smaller compared to Homo erectus but larger
than in modern humans.
Homo heidelbergensis is known to have lived from at least 600 Kya in Africa and
Europe to maybe as late as 250 Kya in some areas. They routinely butchered large animals
with Acheulian Lanceolate hand axes, wooden spears, and Mousterian stone tools. Homo
heidelbergensis was an accomplished tool-maker and organized skillful hunter, and almost
certainly used fire and therefore was the first early human species to live in colder climates.
His short and wide body is likely an adaptation for conserving heat.

The skull of Homo heidelbergensis is intermediate between Homo erectus and the
anatomically modern Homo sapiens. There is no clear dividing line between late Homo
erectus and Homo heidelbergensis; so many fossils between 500- 200 Kya make it difficult to
pick up one as direct ancestor of Homo sapiens. DNA reveals that Neanderthal and Homo
sapiens shared a common ancestor about 400 Kya in Homo heidelbergensis which diverged
to Homo neanderthalensis in Europe and to Homo sapiens in Africa, including perhaps the
Denisovans in Asia.
Emergence of Modern Homo sapiens
Compared to the Neanderthals and other late archaic humans, modern humans
generally have more delicate skeletons with less massive musculature, the skulls more
rounded and the brow ridges less protruding, lacking the occipital buns of the Neanderthal
skulls; the foreheads higher, faces smaller with pointed chins. With such features, the Cro-
Magnon are the first fossils (clearly modern humans) which emerged around 27 Kya in a
rock shelter near Les Eyzies in southwestern France. They looked like modern Europeans,
the males taller (1.6-1.8 m.) than Neanderthals, brains larger up to 1590 cm3, larger than
today’s people; the foreheads higher and faces broad with pointed chins.
But how old are the earliest modern humans? When and where did the “archaic”
Homo sapiens =Homo heidelbergensis evolve to anatomically modern Homo sapiens, is still
hotly debated. As for the Homo erectus-Homo heidelbergensis transition, the first emergence
of modern humans is again generally considered to be an African event probably between
200-150 Kya in the Middle Palaeolithic. The Idaltu or Omo 1 man in Ethiopia is considered
to be the first modern Homo sapiens dating around 160 Kya, but Lee and Wolpoff (2007)
contested it in favour of the Herto Man (around 160 Kya) from the Middle Awash area of
Ethiopia as the better ancestor. Herto had modern rounded skull with archaic large brow
ridges. Somewhat more advanced transitional forms have been found at Laetoli in Tanzania
about 120 Kya and in South Africa about 115 Kya indicating southward expansion of
modern Homo sapiens within African continent. Around 100 Kya modern Homo sapiens had
expanded their range into Southwest Asia (Israel). But, there is no reliable evidence of
modern humans elsewhere in the Old World until 60-40 Kya.
The colonization of the Old World by the African Homo sapiens by replacing the
indigenous regional late Homo erectus and Homo heidelbergensis populations is called

‘Single Origin’ or “African Eve” theory or “Noah’s ark” model. The ‘Out of Africa’ theory
clashed for long with the “Regional Continuity” or ‘Multiregional’ theory, which postulates
that modern Homo sapiens evolved from the regionally differentiated populations of late
Homo erectus or Homo heidelbergensis = archaic Homo sapiens. Currently,
palaeoanthropologists agree on partial ‘assimilation’ which does not preclude some
multiregional evolution and some admixture of the migrant modern Homo sapiens with the
existing regional archaic populations. This has been very recently re-asserted by Alan
Templeton (2012) who concluded:
“Gene flow is a genetic interchange between local populations within a species. ….These studies also
revealed that when anatomically modern humans first expanded out of sub-Saharan Africa starting
130 000 years ago, they interbred at low levels with the archaic Eurasian populations that they
encountered, thereby falsifying the hypothesis that anatomically modern humans completely replaced
genetically the archaic populations that they encountered. This conclusion has been confirmed by
direct studies on ancient DNA and fossils.”
DNA suggests a genetic homogeneity among all present-day people of the world
belonging to a single L3 lineage of relatively recent evolution. Genetic differences among
them occurred as smaller groups of people moved into new environments, such as skin
colour, nose form, and the ability to breathe more efficiently at high altitudes. These adaptive
traits are considered as a very small component of the Homo sapiens genome. Recent DNA
evidence also suggests that several haplotypes of Neanderthal origin are present among all
non-African populations and Denisova hominins, and may have contributed up to 6% of their
genome to present-day humans. We are yet to document through fossils the 60-70 Kya L3
mtDNA lineages in South Asia.
The Status of Narmada Prehistoric Men
The recent human fossil evidences from the Central Narmada valley (Sankhyan et al.,
2012a,b) have confirmed the presence of three hominins in Pleistocene, two archaic and one
early modern (Figures 1 to 4). Among the two archaic types, one was a ‘large-bodied’
hominin represented by the partial skull cap (calvarium) and a recent femur fossil, and the
other was a ‘short and stocky” pygmy-sized Homo sapiens represented by two clavicles
(collar bones) and a left 9th
rib. The third is an ‘early modern’ Homo sapiens represented by a
recent finding of the left humerus.

1. The ‘Large-bodied’ Narmada Hominin
The Narmada partial skull cap (calvarium) has been debated as late Homo erectus (Lumley
and Sonakia, 1985b; Dambricourt Malassie, 2009) or archaic Homo sapiens (Kennedy et al.,
1991; Kennedy, 2000, 2007). Cameron et al. (2004) have taken out Narmada calvarium from
the Homo erectus domain and included it in the Steinheim and Homo heidelbergensis and
considered it a European migrant to South Asia. The author (Sankhyan, 2005, 2007) re-
viewed the calvarium for metric and non-metric traits and noted its maximum metric
similarities with Petralona, followed in the decreasing order by La Ferrassie, the La Chapelle
Aux Saint, the Kabwe/Dali/Zkd 10 / Ngadong11/Sangiran17, the Ceprano and Steinheim.

142
But, Martinez & Arsuaga (1997) regarded the Petralona and other European forms grouped
under Neanderthals showing local affinities.
Figure 3A: Excavations conducted by the author and his team at U1 level of Hathnora hominin calvarium site
yielded in situ mandible of Elephas namadicus and other mega fauna including over a hundred ‘Large Flake
Acheulian’ handaxes, cleavers and chopping tools for the first time (Sankhyan et al., 2012b) Figure 3B:
Author’s revisit to Netankheri hominin locality in October 2012 yielded more Palaeolithic findings recovered in
situ from the humerus bed shown in Figure 4B (bottom left).

hominin provisionally named here Homo narmadensis. B. The ‘small-bodied’ Mode 3 Homo bamanensis and
‘early modern’ Homo sapiens (modified from Sankhyan et al. 2012b).
Overall, Narmada skull cap is classifiable gradistically with the “archaic” Homo
sapiens or Homo heidelbergensis or cladistically either Homo heidelbergensis (Athreya 2007)
or a distinct unknown species, Homo indet. The recent femur from Netankheri just 3 km
upstream from Hathnora shows a robust morphology of the ‘large-bodied’ hominin
intermediate between Homo erectus and the Homo neanderthalensis. Quite likely therefore
the Hathnora calvaria and the Netankheri femur are derived from the same hominin species
which was very akin to Homo heidelbergensis, if not a new species.

1. The ‘short and stocky’ Narmada archaic Hominin
The two clavicles and the 9th
rib are important for estimating the body dimensions of the
hominin (Sankhyan, 1997a, b, 2005, 2007; Sankhyan & Rao, 2007) useful in understanding
hominin adaptations. The clavicles yielded a fair estimate of the upper chest or breadth across
the shoulders as well as the antero-posterior depth of the thorax; the 9th
rib reflects the
maximum expanse of the lower thorax or the shape and size of the trunk. In addition, the
clavicle length also provides a fair estimate of the stature. The conoid indices of the Narmada
clavicles closely go with the mean value of modern humans or the lower value of the
Andaman pygmy, suggesting a modern type moderate chest depth and adapted to warm-
humid tropical climate. Its diaphyseal robusticity indicates body build and life styles or
occupations and ecological adaptations of the early hominins (Pearson, 2000). The midshaft
index further attests the same showing diaphyseal rounding touching the lower threshold of
Homo sapiens. The diaphyseal rounding shows interesting evolutionary trend from the
primitive platycleidy of Plio-Pleistocene hominids, the mesocleidy of the Neanderthals and
the eurycleidy of modern humans (Sankhyan, 1999b).

Employing various methods, the author achieved the varying stature estimates
ranging from 115 to 135 cm (Table 1). The maximum estimate tallies with the lower value of
the female Onge and the Greater Andamanese, both skeletal and living. Similarly, a value of
30.6 cm shoulder width estimated for Narmada right clavicle corresponds to the mean
biacromial diameter of female Onge with a narrow range of 29 – 33.5 cm (Chatterjee, 1956)
indicating that the Narmada hominin had body dimensions similar to those of Pygmy.

144
Given the above evidence there is definite presence of the ‘short and stocky’ archaic
hominin in Central Narmada valley that was different from the ‘large-bodied’ one. But, due
to no specific nomenclature it was often confused and neglected. The author therefore feels
the necessity of a formal nomen provisionally given here as Homo narmadensis who was the
potential carrier of the Mode 3 culture in South Asia and probably of the early Mode 4 as
well as that documented at Netankheri.
The Netankheri humerus was found in association with Middle Palaeolithic (Mode
3) tools and with bone implements found for the first time in Narmada valley. They are dark
in hue and possess evidence of fire treatment or charring besides dental marks on a few. Most
of the bone tools include humeral and femoral distal and mid shaft splits, but antler, scapular
and rib fragments are also used. They have the evidence of retouches on the working edge.
Typo-technologically they appear of late Mode 3 or early Mode 4; there are different types,
viz., a hand-held dagger, spatulas, scrapers, drills, awls, burins and blades. The associated
mixed later Middle Palaeolithic and early Upper Palaeolithic stone and the bone tools
indicate continuity and diverse technological skills and adaptations to the changing
sedimentary regime, found in early anatomically modern Homo sapiens.
The absolute dating of the Netankheri humerus is yet to be done. But, its location is
below the Youngest Toba Ash (YTA)which is datum of ~75 Kya located higher in the
overlying Baneta and Hirdepur formations in Narmada and its tributaries (Tiwari & Bhai,
1997). If that is true then the Netankheri humerus could be older to the YTA datum. The
fauna and archaeological findings also allow a date interval for the humerus between 80 and
70 Kya.
DISCUSSION AND CONCLUSIONS
Thus, the known evidences indicate presence of two types of archaic hominins. An
early modern human lived in Narmada valley during Middle to early Late Pleistocene times
(~250 to 70 Kya). The “large-bodied” species (Homo heidelbergensis) was wide spread
during the Middle Pleistocene in the lower level (U1) of the Surajkund formation which
hunted mega mammals with typical Mode 2 Acheulian implements. A distinct change
occurred in the climate and ecology at the Mode 2 / Mode 3 transition visible in the faunal
content, which was not favourable for the Large Flake Acheulian hunter who consequently

145
migrated to other parts. Author’s recent archaeological studies at Susunia (Sankhyan 2009a,
b) have demonstrated northward movements of the Late Acheulian man, some branches of
which also migrated southeastward to the Bastar region (Sankhyan et al., 2011).
The changed ecology gave way to a ‘short-stocky’ Mode 3 man (Homo narmadensis)
who emerged at around 150 Kya in Narmada valley and possibly colonized the entire
peninsular India throughout the Middle to Upper Palaeolithic. Possibly, the entire South Asia
was colonized by populations of Homo narmadensis which evolved and split to several
similar-sized populations, such as the proto-Australoids and the pygmies. The latter colonized
the Southeast Asia and Andaman Islands, and it is not unlikely that the African Pygmy have
ancestry in Homo narmadensis in Indian heartland.
The genomic evidence supports a model of early divergence of African KhoeSan (the
Bushmen) ancestor from a proto-Pygmy non-Pygmy group about 110 Kya (Veeramah et al.
2011) contending that the KhoiSan were oldest human race followed by the Pygmy. The
latter expanded to the equatorial Africa, and also believed to have migrated very early to the
Southeast Asia, such as New Guinea and Philippines (Aeta), Malaya (Semang), Thailand
(Mani), Andaman archipelago (Jarawa/Ang, Onge, Greater Andamanese and Sentinel), Flores
Island (Rampasasa) and Vanuatu archipelago, when most of these islands were not separated
or were fissured by narrow seas.
Champions of “Out of Africa” hypothesis also speculated early entry of African
‘modern’ Homo sapiens in the later Middle Pleistocene of South Asia carrying Mode 3
technology (James & Petraglia 2005), and so for the early Khoisan (Bushmen) and Pygmy
ancestry in Africa and beyond. If more evidences corroborate then the Homo bamanensis
may turn out to be the possible common ancestor of the KhoeSan and the Pygmy who entered
into the Central Narmada valley around 150 Kya possessing Mode 3 technology? If so,
further evolution of the anatomically modern Homo sapiens is now documented by the recent
humerus about 80 Kya and the "volcanic winter" was not a major hurdle even though it could
have been a great disaster first experienced by the hominins in South Asia (Chesner et al.,
1991; Ambrose, 1998; Oppenheimer, 2002, 2003). Possibly, the eruption of the Toba Mount
in Sumatra- the largest volcanic blast on Earth in the last two million years, had wrapped
India in a 6-inch (15 cm) sheet of volcanic ash leading to a 6-year “Volcanic Winter”. So, it
was the popular “bottle-neck” argument (Ambrose, 1998) to favour African “exodus” as the

146
Indian archaic hominins were arguably considered possessing primitive technology than the
migrating African humans. But, the Narmada archaeological evidence indicates that the
Homo narmadensis was quite innovative and culturally adapted to withstand the “Volcanic
Winter”. The innovation of the bone artifacts was a unique cultural adaptation to facilitate
rapid attainment of anatomical modernity. The ‘short bodied’ humans also had added
advantage of lesser metabolic requirements vis-à-vis the ‘large-bodied’ Acheulian hominins.
While we need to find out more fossil evidences beyond 70 Kya, it is at least clear that
the central India was predominated by the “short-bodied” human populations since about 70
Kya. They may have formed the ancestral substratum of the Andaman-Nicobar pygmies, the
Proto-Australoid /Austric Pauri Bhuya/Munda, including the Australian aboriginal
populations. The mtDNA M31 signatures of >60 Kya found in the Pauri Bhuya/Munda
(Barik et al., 2008; Chandrasekar, 2009) attest the continuity of the “short-bodied”
populations inhabiting the easternmost fringe of the Narmada Valley, and it is also an
interesting revelation that these signatures are shared with the Andaman pygmy, who appear
to have differentiated from the mainland common stock just around 25-30 Kya though their
settlement in the Andaman Islands is not yet known archaeologically beyond 2,200 years BP
(Cooper, 2002). The antiquity of their collateral groups living in the Phillipines, is however
estimated to be 35 Kya (Omoto 1984). According to Bellwood (1978) the Andamanese are
the early Austro-Melanesian settlers of Southeast Asia and Oceania, and not closely related to
the African pygmy populations.
Modern Andamanese are closer to the Asians than to the Africans. The D-loop and
protein-coding data reveal that their phenotypic similarities with the African Pygmies are
likely convergent (Endicott et al., 2003, Thangaraj et al., 2002). This view is also supported
by genomic studies on the Onge by Thangaraj et al. (2005), on the Jarawa by Barik et al.
(2008) and by Chandrasekar et al. (2009) that they possess haplogroup M31 and M 32 shared
with the South-West Asians and Indian mainland Rajbanshi and Pauri Bhuya rather than with
the Africans (Figure 5). A great bio-cultural diversity of India is also in itself an indicator of
her deep prehistory. The totality of evidences—social, cultural, historical, archaeological,
linguistic, phenotypic, epigenetic and genetic—support a conclusion that the Andaman
Islanders have been isolated for a substantial period of time from the African groups. It is
also clear that South Asia was first inhabited for a long time by diverse short-bodied
populations some of which differentiated into the pygmies and the micropygmies, such as the

tiny “Hobbits” (Homo floresiensis) (Brown et al., 2004) of Indonesia who occupied the Liang
Bua cave in Flores Island close to the Rampasasa Pygmy. The movement continued down to
the Near Oceania / Sohul (PNG and Australia). This scenario is unlike the previous view that
they bypassed South Asia via southern route to arrive Australia (Lahr and Foley, 1994).
Figure 5: Genomic relationship (in mtDNA M32 haplotype) of the Onge and the Greater
Andamanese Pygmy with the mainland Rajbanshi and Kurumba and their divergence times
The contenders of “Out of Africa” hypothesis argue that anatomical modernity in
South Asia was due to the migrating ‘large-bodied’ African Upper Palaeolithic Homo sapiens
as they had attained early symbolism, complex tool-making behavior and sophisticated social
behaviour in Africa. This view continued due to lack of fossil evidence in South Asia after
the Toba event 75 Kya until very late occupants of the Fa Hien cave of Sri Lanka around 28-
30 Kya (Kennedy & Deraniyagala 1989) and Darri-I-Kur of northeastern Afghanistan (Angel
1972). But, India is geographically and climatically very diverse, and we may not rule out the
possibility of the late survivors of indigenous late Acheulian ‘large-bodied’ men in South
Asia who could achieve anatomical modernity in some pockets. Dambricourt Malassie vide
Chamyal (2011) cites an example of such survivors as late as about 4500 years ago. She
considers that a skull found at Orsang on the western Narmada end in Gujarat in a burial
retains vestiges of the ‘robust features’ of Homo erectus found in the Hathnora calvarium. If
such arguments hold footing, it is quite likely that the descendants of both these ‘large’ and
‘small’ ancient Narmada lineages contributed to the diverse gene pool of South Asia.

The Narmada Pleistocene hominins thus would throw open several possibilities and
secrets of human evolution in South and Southeast Asia. It is also because Narmada valley
occupies a strategic mid- place in South Asia as well as between Africa/Europe in the west
and the South-East Asia in the east, and was the major East-West inter-continental link and
passage. The equable climate of Narmada valley, the Central Narmada valley and thousands
of prehistoric rock shelters of the Satpura and Vindhyan hills served the ancient abodes and
centres of artistic activities down through history. I therefore viewed the region as a “paradise
of the Prehistoric man” in South Asia (Sankhyan, 1999a, b, 2005).
